The best IBM Cloud Object Storage resiliency option for a use case where data must remain in-

country and locally restricted is Single Data Center.

Single Data Center: This option ensures that all data is stored within a single geographic location,

which complies with regulations or requirements that mandate data residency within a specific

country. By using a single data center, the data remains locally restricted.

Data Residency Requirements: When an application has strict regulatory or compliance requirements

that specify data must not leave the country, the Single Data Center option ensures that data does

not cross geographic boundaries.

Reference from IBM Cloud Professional Architect Materials:

IBM documentation on IBM Cloud Object Storage Resiliency Options states that the Single Data

Center option is best suited for scenarios where data residency is a concern.

Other options are incorrect:

A . Cross Zone,

C. Cross Region, and

D. Multizone involve data being stored across multiple locations

or regions, which would not meet the requirement of keeping the data locally restricted.
